O'Hare Airport Parking Lot G: Rates, Shuttle & Tips 2026

Back to Complete ORD Airport Parking Guide

Economy Lot G is the cheapest on-airport parking option at Chicago O'Hare International Airport, costing just $15/day — compared to $43/day in the terminal garages. It's an open-air, self-park lot served by the free Airport Transit System (ATS) people mover, which connects directly to all terminals every 3-5 minutes, 24/7. Lot G is the best pick for budget-conscious travelers who don't mind a short ATS ride to their gate.

• Rate: $3 for the first hour, then a $15/day maximum — the lowest daily cap of any on-airport lot (verified May 2026)
• Access: Free ATS people mover picks you up at the Lot G station and reaches all terminals in minutes
• Savings vs. garage: Lot G saves you up to $28/day compared to the Terminal garages
• Open-air lot: No covered roof — plan for Chicago weather, especially in winter
• Accessible parking: Clearly marked accessible spaces are available in Lot G near the ATS station
• Advance booking: Reserve ahead via flychicago.com or SpotHero to lock in your spot

What Is O'Hare Airport Parking Lot G and Where Is It Located?

Economy Lot G is an on-airport, open-air self-park facility operated by the Chicago Department of Aviation (CDA). It sits on the west side of the airfield, off Bessie Coleman Drive, and is part of O'Hare's network of economy lots alongside Lot E and the covered Lot F. Lot G is the most remote of the three, which is exactly why it's the cheapest.

You reach Lot G directly from I-190 (the Kennedy Expressway spur that feeds straight into the airport). Follow signs for Economy Parking when you exit. Once parked, you walk a short distance to the dedicated Lot G ATS station, where the free people mover picks you up. There is no separate shuttle van — the ATS is your ride, and it runs every 3-5 minutes around the clock.

O'Hare's total on-airport parking capacity is approximately 18,000 vehicles across all garages and economy lots, per the Chicago Department of Aviation. Lot G is a meaningful share of that, making it one of the larger surface lots at the airport. During peak travel periods — holiday weekends, summer Fridays — it can fill by mid-morning, so arriving early or booking ahead matters.

Active ORDNext construction on the new Concourse D (vertical build underway spring 2026) is focused near Terminal 1. Lot G access via the ATS remains normal, but allow a few extra minutes when navigating terminals in 2026.

How Much Does Economy Lot G Parking Cost at O'Hare?

Lot G costs $3 for the first hour and maxes out at $15 per day — the lowest daily cap of any on-airport parking option at ORD (verified May 2026, per flychicago.com). That makes it ideal for multi-day trips where every dollar counts.

A 5-day trip in Lot G costs $75 total. The same trip in a terminal garage runs $215. That's a 65% saving just by walking to the ATS instead of walking directly to your terminal. For a 7-day trip, the gap grows to $140 vs. $301.

There are no published weekly discount rates or extended-stay flat fees for Lot G — you simply pay the $15/day maximum each day. The CDA does not publicly advertise seasonal surcharges, but availability tightens around Thanksgiving, Christmas, and July 4th. Booking in advance through SpotHero locks in the standard rate and guarantees your space. For a full breakdown of all economy lot pricing, see the O'Hare Airport Parking Rates & Cost Guide 2026.

How Do You Get from Lot G to the O'Hare Terminals?

The free Airport Transit System (ATS) is the only way to get from Lot G to the terminals — and it works well. The ATS is an automated people mover that runs on a fixed loop, stopping at Terminals 1, 2, 3, and 5, the Multi-Modal Facility, all economy lots, and the Kiss 'n' Fly drop-off zone.

Here's how the process works step by step:

1. Park your car and note your row and space number — or take a photo. Lot G is large, and the rows look similar when you return.
2. Walk to the Lot G ATS station. Signs are posted throughout the lot.
3. Board the ATS train. No ticket needed — it's completely free.
4. The ATS loops through the terminals in order. Ride to whichever terminal matches your airline.
5. At your terminal, follow signs to check-in and security.

ATS trains run every 3-5 minutes, 24 hours a day, 7 days a week. Total transit time from the Lot G station to Terminal 1 or 3 typically takes around 10-15 minutes when you factor in the walk to the station and the loop route. Add another 5 minutes for Terminal 5. Plan for this when timing your departure from the lot.

For international travelers flying out of Terminal 5 (Delta, Emirates, Air France, KLM, Turkish Airlines, and others), Lot G still works well — just allow extra time. Terminal 5 is the last stop on the ATS loop. Arrive at the lot at least 2.5 to 3 hours before an international departure.

How Does Lot G Compare to Lots E and F at O'Hare?

All three economy lots use the same free ATS connection, but they differ in price, cover, and convenience. Here's what sets them apart:

• Economy Lot G ($15/day): Cheapest option. Open-air, no roof. Best for short or long trips where you want to minimize cost. No protection from rain or snow.
• Economy Lot E ($17/day): Also open-air. Slightly closer to the ATS loop than Lot G in some reports. Two dollars more per day than Lot G.
• Economy Lot F ($22/day): Covered structure. Protects your car from Chicago weather year-round. Costs $7/day more than Lot G. Best for winter trips or anyone worried about hail, snow, or sun damage.

For a 5-day winter trip, the difference between Lot G and Lot F is $35. Some travelers consider that a fair price for a dry, snow-free car. For summer or short trips, Lot G's savings are hard to argue with.

Is Off-Site Parking Cheaper Than O'Hare Economy Lot G?

Yes — the cheapest verified off-site lots near ORD start at $8.95/day, which is 40% less than Lot G's $15/day rate. The trade-off is a 7-15 minute shuttle ride instead of the on-airport ATS.

Park 'N Jet O'Hare and Routes Airport Parking both sit along Mannheim Road, roughly 7-10 minutes from the terminals by shuttle. PreFlight Airport Parking runs one of the fastest shuttle services near ORD — every 5-10 minutes — and also offers EV charging, luggage assistance, and a car wash. All three offer free cancellation.

For a 7-day trip, parking at Park 'N Jet saves you $42.65 versus Lot G. That's real money. The main downside: you're relying on a private shuttle van rather than the automated ATS. During early morning departures or red-eye returns, most travelers report the off-site shuttles run reliably — but the ATS never stops. For more detail on all the off-site options, see the Off-Site O'Hare Airport Parking guide.

How Do You Reserve O'Hare Lot G Parking in Advance?

Reserving Lot G in advance is strongly recommended during peak travel periods. Lot G can fill by mid-morning on holiday Fridays and summer weekends. A confirmed reservation means you drive straight to your space without circling or being redirected.

You have two main options for booking ahead:

• flychicago.com: The official CDA parking portal. Book directly through the airport authority for guaranteed rates.
• SpotHero: A third-party comparison tool that often lists Lot G and nearby off-site options side by side. Useful for comparing prices in one view.

When you book online, you typically receive a confirmation code or barcode. At the Lot G entry gate, scan your code or enter your confirmation number to proceed. Payment methods accepted at ORD lots include cash, Visa, Mastercard, Amex, Discover, Apple Pay, and Google Pay. Mobile contactless payment works at the exit gates.

Before you drive, it's smart to check real-time traffic on Waze — especially on holiday weekends when I-190 and I-90/94 can back up significantly. Arriving with extra time is always the right call when Lot G is your plan.

What Are the Rules and Tips for Long-Term Parking at Lot G?

Lot G is well-suited for long-term stays. At $15/day, a two-week trip costs $210 on-airport — which is competitive but not unbeatable by off-site lots. Here's what to know before leaving your car for multiple days:

• No published maximum stay limit under 30 days for standard economy lots at ORD, but contact the Chicago Department of Aviation for extended stays beyond 30 days
• Open-air exposure: Chicago winters are brutal. Snow, ice, and freezing temperatures are real concerns for outdoor parking from November through March. Consider Lot F (covered) for winter trips
• Note your exact spot: Take a photo of your row and space number. Lot G is a large, flat surface lot. Rows look identical when you return exhausted after a long flight
• EV charging: EV charging has not been confirmed in Economy Lot G as of May 2026. PreFlight Airport Parking off-site does offer EV charging. On-airport EV charging is available in select garages — check with the CDA before you go if this matters to you
• Accessible parking: Clearly marked accessible spaces are available in Lot G, located near the ATS station entrance for the shortest walk
• TSA PreCheck: If you're a frequent traveler, TSA PreCheck speeds up security lines significantly — worth combining with Lot G's low daily rate for a genuinely cost-efficient departure routine

For trips longer than a week, it's worth running the numbers against off-site covered lots. A 10-day stay at Park 'N Jet ($8.95/day) costs $89.50 versus $150 at Lot G. That's a $60.50 difference — enough to cover airport meals or a checked bag. If cost is your primary driver for extended stays, see the full analysis in our ORD Long-Term Parking Options: Full 2026 Guide.

Pro tip: Before a winter trip, remove any valuables, top off your washer fluid, and leave your wipers up. Lot G has no de-icing service. Coming back to a frozen windshield after a week away is avoidable with a little prep.
